Not So Goody-Goody

I'm eighteen, and my parents have no idea what I do. I have a boyfriend. We've been dating for five months. Every night he comes over and we do all kinds of nasty stuff you could only image. My dad was in the other room, and thank the Lord that he was asleep. I'm sure he would have heard us. We always have sessions every night. My parents think that I'm such a goody-goody.
